CHANGES IM CftAG HICRBICIDE #1 



Crag Herbicide #1, as such, is short lived virhen it comes in contact with the 

 soil. It is changed in a few hours by bacteria to an "active form". However, the 

 bacteria are not satisfied to leave it in this "active form". They break it down 

 further into 2,U-D. Both the "active form" and 2,U-D are plant growth regulators 

 and can cause the typical plant modifications v/hich result when such materials are 

 used in excess. 



On strav/berries the first visible symptoms of CH #1 injury is usually a 

 slight bending backward of the leaf stem. As the stem continues to grow, the outer 

 and bends upward. The result is a stem which looks like an elongated letter S and 

 lies close to the ground instead of standing up as a strawberry leaf stem should. 

 This bending back is called epinasty. It is an effect commonly produced on sensitive 

 plants by materials such as 2fk-d, 2,l4,5-T, MCP, and other grov;th regulators. 



In severe cases of injury on strawberries, wilting was observed about a week 

 after OH #1 was applied. The Tfilting was caused by the failure of the injured plants 

 to develop fine, fibrous roots. This type of injury was observed on a very light 

 soil when a h pounds per acre application of Crag Herbicide //I was followed by very 

 heavy rain , It is probable that the 3 pounds per acre rate is risky on such light 

 soils. On a Gloucester sandy loam soil, part of a rov/ of plants was injured by 

 overgpraying with a hand sprayer, although the rate of application attempted was 3 

 pounds per acre. 



As a result of these recent experiences, it seems best on very light soils to 

 use GH #1 at not to exceed 2 pounds per acre and only on an experimental basis until 

 more iiiformation is available, Tito and a half pounds per acre is enough on light 

 soils. On medium and heavy soils, a rate of 3 pounds per acre appears safe,

TO BEY'S TRAVELS - Chapter IX 



For the period 19kO-19h9 the average apple production in Oregon exceeded that 

 of ilassachusetts by about 200,000 bushels, Since 19k9 the annual apple production 

 in Massachusetts has exceeded that of Oregon by nearly 1 million bushels, ..'hile pro- 

 duction in Oregon has been holding about steady production in Massachusetts has in- 

 creased. 



The relative importance of the various fruits grown in Oregon is shown in the 

 following table: 



Tree Fruits (acres) Small Fruits (a cres) 



Regardless of the fact that Oregon does not rank among the larger apple pro- 

 ducing states, nevertheless, Oregon does rank high as a fruit producing state due to
